Why Am I Not Hungry After Fasting?

Fasting has become a popular health trend in recent years, but it's not uncommon to experience a lack of hunger after abstaining from food for an extended period of time. This phenomenon can be both confusing and concerning, especially if you're trying to stick to a fasting schedule. In this article, we'll delve into the science behind why some people don't feel hungry after fasting. Whether you're a seasoned pro at fasting or just starting, read on to learn more about why hunger may not always be present during this lifestyle change.

1. Hormonal Changes

One of the main reasons why some people may not feel hungry after fasting is due to hormonal changes that occur in the body. During fasting, the body shifts from using glucose, as its primary source of energy, to using stored fat. This process is known as ketosis and it results in the release of hormones such as glucagon and norepinephrine, which can suppress feelings of hunger. 

2. Autophagy

Another reason why some people may not feel hungry after fasting is due to the process of autophagy. Autophagy is the natural process of the body's cells breaking down and recycling old or damaged cells. This process occurs when the body is in a state of starvation and it can lead to a decrease in feelings of hunger as the body is able to extract energy from these recycled cells.

3. Gut Health

Gut health also plays a role in feelings of hunger during fasting. When the body is in a state of starvation, the digestive system slows down and less energy is required for digestion. This can lead to a decrease in feelings of hunger as the body is not focused on processing food. 


In conclusion, there are several reasons why some individuals may not feel hungry after fasting, including hormonal changes, autophagy, and gut health. Fasting can be a beneficial practice for health and well-being, but it is important to consult with a healthcare professional before starting a fast, particularly if you have any underlying health conditions or are taking any medications.
